The K&N Drycharger RX-4730 silicone-treated polyester wrap protects K&N air filters and flame arrestors by limiting water ingress while preserving airflow through uniform micron-sized openings. Offered in black, this Drycharger adds water-repellent protection that typically lasts one to two years, helping maintain filter performance in wet or humid conditions without significantly restricting intake flow.
